Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66996, here are decompositions:
- 19 + 66977 = 66996
- 23 + 66973 = 66996
- 37 + 66959 = 66996
- 47 + 66949 = 66996
- 53 + 66943 = 66996
- 73 + 66923 = 66996
- 107 + 66889 = 66996
- 113 + 66883 = 66996
Showing the first eight; more decompositions exist.
